Abstract

A coated component, along with methods of making and using the same, is provided. The coated component includes a ceramic matrix composite (CMC) substrate comprising silicon carbide and having a surface; a mullite/NOSC bondcoat on the surface of the substrate; and an environmental barrier coating on the mullite/NOSC bondcoat. The mullite/NOSC bondcoat comprises a non-oxide silicon ceramic (NOSC) phase contained within a mullite phase, with the mullite/NOSC bondcoat comprising 60% to 95% by volume of the mullite phase, such as 65% to 93% by volume of the mullite phase.
